Continuing along on her tour all through the States, Lady GaGa put on a sizzling show at the House of Blues in Boston on Monday night (March 30).

Proudly shaking her rear-end for the packed house, GaGa seems to be fully embracing her quick rise to the top of the music world.

The 23-year-old’s hit song “Poker Face” just repeated as tops on the UK singles chart for the second straight week.

She’s plus set to seem alongside past winner David Cook on the hit show “American Idol” tomorrow night (April 1) at 9PM EST on FOX.
